Resolving The Problem
If all steps have been exhausted to diagnose if there is a disk enclosure related HW issue, follow the below steps to clear the system error LED (amber)
STEPS:

$nzstop
2) Power cycle; power-off/power-on the S-blades and the storage groups
2.1) power OFF S-blade Chassis
$/nzlocal/scripts/rpc/spapwr.sh -off all
2.2) power OFF storage groups
$/nzlocal/scripts/rpc/spapwr.sh -off all -j all
- wait for 5 minutes; to allow enough time to clear system error LED
2.3) power ON storage groups first
$/nzlocal/scripts/rpc/spapwr.sh -on all -j all
- wait for 5 minutes before power ON S-blade Chassis
2.4) power ON S-blade Chassis
$/nzlocal/scripts/rpc/spapwr.sh -on all
3) Start NPS
$ nzstart
4) Check system for HW issues
